Abstract

The catalytic action of nitroprusside on the phenol hypochlorite reaction has been utilised to design a more sensitive automated technique for determining ammonium nitrogen in soil extracts. The method gives reproducible results in close agreement with manual methods. Sensitivity is such that as little as 0.1 parts/ million of N in solution can be determined without the use of recorder range expansion.

The first practical method for the determination of hexosamines was worked out by Elson and Morgan (1). Since that time many modifications have been introduced in an attempt to increase the sensitivity and reproducibility of the technique (2) and to decrease the effect of interfering substances (3)
